Overview
This aftermarket replacement spool comes pre-loaded with trimmer line at the correct diameter and winding pattern for your trimmer. When the original spool runs empty or the line becomes brittle from UV exposure, swapping in a fresh spool is faster than re-winding. The pre-wound design ensures consistent bump-feed performance from the start.
Key specifications
- Pre-wound replacement trimmer spool
- Direct-fit for listed trimmer models
- Bump-feed compatible winding pattern
Compatibility
This spool is designed for Black+Decker string trimmers as listed above. Confirm the spool part number, line diameter, and trimmer model before ordering to ensure a proper fit.
Installation notes
Turn off the trimmer and remove the spool cover by pressing in the retaining tabs. Remove the old spool and wipe out the housing. Insert the replacement spool, thread the line ends through the eyelets, and snap the cover into place. Test the bump-feed mechanism by tapping the head and pulling the line.
Common questions
Q: Will this AF-100 AFS spool fit my Black+Decker LSTE525 and LST140C, or is it only for older models like the ST8600?
Yes, this AF-100 AFS spool is compatible with the Black+Decker LSTE525, LST140C, and ST8600, along with other listed models that use the AF-100 style automatic feed system. If your trimmer is one of the listed models, this is the correct spool type to use.
Q: Do I need to wind line onto this AF-100 AFS spool myself before installing it in my MTC220 or LCC340C?
No, this style spool comes ready to install, so you do not need to rewind line before use. Just remove the spool cap, seat the AF-100 spool correctly in the trimmer head, feed the line through the eyelet, and reinstall the cap securely.
Q: My LST136 keeps feeding too much line or getting tangled—will replacing the spool help, and is there anything I should check during installation?
A worn, incorrectly wound, or damaged spool can definitely cause overfeeding and tangling on the LST136. When installing the new AF-100 AFS spool, make sure the line exits smoothly through the eyelet and check that the spool cap and spring are clean and seated properly, since debris inside the head can also affect feeding.
